| 摘 要： | 通过详细的野外填图和地球化学研究，发现皖南伏岭岩体具有高硅、富铝、富碱，富集高场强元素，富集REE，高Rb、低Sr、Ba的特点，属于铝质A型花岗岩。地球化学特点表明岩浆由下地壳部分熔融产生；岩体是在造山后伸展构造环境中沿断裂快速上升定位、分异作用不完全状态下形成。

| Abstract: | Detiled field geological mapping and geochemical study show that the Fuling rock mass in southern Anhui is enriched in Si ,Al,alk , high-field strength elements ,REE ,Rb and depleted in Sr and Ba,belonging to aluminous A-type granites. These characteristics suggest that the magma originated by partial melting of the lower crust. The rock mass rose and was emplaced rapidly along fault in a post-orogenic extensional environment,and the magrnatic differentiation was incomplete. |
